Title: Arrangement for regulating medium flow especially the flow of air of a radial flow fan
IPC: F04D27/02
Filed: 1973-02-19
Abstract: 1421573 Centrifugal fans SVENSKA FLAKTFABRIKEN AB 19 Feb 1973 [25 Feb 1972] 7957/73 Heading F1C The flow through a fan or other device for generating a flow of medium is regulated by means of a cylindrical ring freely inserted within and in contact with the device and rotatable therewith, the ring being shorter in axial length than the device and variable in length or position to effect the regulation of flow. In the fan shown in Fig. 2, a variable part of the axial length of the impeller 5 can be blanked off by means of a telescopic ring 13 attached to the impeller back plate 6. In another embodiment, a ring cut to the desired axial length or selected from a number of rings of different length, or a number of rings put together to aggregate the required length, can be placed within the impeller abutment with the back plate 6. The rings may additionally vary in radial thickness. A single ring of fixed axial length equal to 20-50% of the impeller length may be placed within the impeller in a desired axial position, the reduction of flow obtained being greater when the ring is adjacent the impeller eye 7 than when it is adjacent the back plate 6.

Abstract: 1,170,024. Feeding record tapes. NEWELL INDUSTRIES Inc. 19 Feb., 1968 [21 Feb., 1967], No. 7961/68. Heading G5R. In a tape transport in which a resilient capstan 24 drives the edges of supply and takeup rolls 17, 18, geared drive trains 37, 39, 44, 47, 49, 52 and 38, 41, 46, 48, 51, 53 urge both rolls against the capstan with the greater force on the take-up roll, resistances in the drive trains aiding the force on the take-up roll and opposing the force on the supply roll since the take-up spindle 21 is retreating from the capstan while the supply spindle 19 is advancing as the tape is wound from the supply roll 17 to the take-up roll 18. The arrangement provides inertial damping against bouncing of the tape rolls away from the capstan, and safeguards against the formation of flats between the rolls and the capstan by removing the compressive forces when the apparatus is switched off.

Title: Improvements in or relating to high frequency oscillators
IPC: H03B5/18
Filed: 1937-03-22
Abstract: 492,610. Valve generating circuits; electric resonators. GENERAL ELECTRIC CO., Ltd., and MEGAW, E. C. S. March 22, 1937, No. 8367. [Classes 40 (iii) and 40 (v)] An oscillator, for example, a split-anode magnetron, particularly for generating very high frequencies, has a pair of electrodes connected to points on a resonator having capacity and inductance (which may be distributed) by a pair of leads the length of which is adjustable so that the system comprising electrodes, leads, and resonator may oscillate as a whole at the desired frequency. In one arrangement, Fig. 1 (Prov.), the resonator comprises parallel conductors 9, 10 having a fixed bridge 11 at one end and a movable bridge 12 to tune it to the desired frequency. The lengths of the leads 5, 6 are adjusted by telescopic members so that the points 7, 8 are at the first potential node, i.e. the electrical length of the leads is one-quarter of a wave-length. The production of harmonics may be prevented by connecting resistances shunted by small inductances in the leads 5, 6 close to the generator. The load circuit 13 is connected across the resonator by tappings 16, 17. In a modification, Fig. 2 (Prov.) (not shown), the bridge 11 is replaced by a variable condenser to the terminals of which the leads 5, 6 are permanently connected. In a third arrangement shown in Fig. 1 (Comp.), the resonator is of fixed frequency and comprises coaxial tubes 5, 6 connected at one end by a grounded plate 7. The magnetron comprises four anode sections connected together in pairs and to conductors 9, 10 having their lengths adjusted by a bridge 11 to threequarters of the wave-length of the fundamental frequency. One connection from a generator electrode to the resonator takes place through ground at 8 and on the cathode the other comprises part of conductor 10 and lead 13 to a point 14 on the inner tube and the length of this connection is adjustable by telescopic means or by varying point 12. This system oscillates at three times the fundamental frequency and the fundamental may be suppressed by connecting a choke across terminals 2, 3. The load may be connected to the resonator or to conductors 9, 10. The resonator tubes may be of copper or steel plated with silver, and suitable dimensions are given in the Specification. Specification 417,564 is referred to.

Abstract: 563,884. Roll-film cameras. KODAK, Ltd. May 20, 1943, No. 8042. Convention date, June 19, 1942. [Class 98 (i)] In roll-film camera in which operation of a winding member in one direction feeds the film from a supply spool across an exposure frame, and in the opposite direction re-winds the film on to the same spool, and in which the film is held against the exposure frame by a pressure member during the exposures, a one-way clutch normally permits operation of the winding member in one direction only, but is releasable by means which also moves the pressure member away from the exposure frame to form an open film channel. In the construction shown, the film is first fed from the supply spool S into a take-up chamber 7 containing a spring 12 which causes the film to form' a loose coil. During this operation a button 26 is depressed, moving a slide 17 to the left so that a pin 27 on it disengages a pawl 14 from a ratchet on the winding shaft to allow it to be rotated anticlockwise. The slide 17 also rocks levers 19 so that their cam-formed ends 18 engage lugs 25 extending from the presser plate, so moving it away from the exposure .frame to release the film. When the button 26 'is released, the slide 17 is returned by a spring and the pawl 14 allows the film to be wound only in one direction, back on to the spool between exposures, and the pressure plate is released and comes into operation.

Filed: 1972-02-23
Abstract: 1386345 Overload release mechanism TECHNION RESEARCH & DEVELOPMENT FOUNDATION Ltd 23 Feb 1972 [5 March 1971] 8445/72 Heading A1P In a tractor three-point hitch the two lower linkages embody means for releasing both implement linkage members should the implement meet an obstruction which causes the traction forces (in either one or both of the linkages) to increase beyond a pre-set value. The upper draft link remains connected to the implement, and re-hitching of the other links can be effected after the obstacle is passed. Connecting pins 6 from the implement are retained, by pawls , in hooks 9 Fig. 3. When the force on pin 6 exceeds a pre-set value, which is selected by adjusting valve spring 22 which controls the pressure on pistons 14 holding the pins in position, then lever 10 pivots about fixed fulcrum 11 and piston 14 is forced up against spring 16 and also against the hydraulic liquid pressure in cylinder 15. The cylinder is connected to the body of the hitching mechanism by means of pin 17, about which it can swing. The increase in liquid pressure causes relief valve cone 24 to be lifted from its seat 23 in pressure relief valve 20 and fluid can then escape into pipe 26. The hydraulic pressure thereby drops and the pins are not securely held and they can slip out of contact with the levers 10. If the traction force increases in only one of the lower links then the subsequent decrease in hydraulic liquid pressure is transmitted to the other link via a T-piece 19 connecting both tubes 18 to the same pressure-relief valve 20. After passing the obstruction spring 22 returns piston 21 to its original position and air pressure inside pressure vessel 27, which contains liquid in its lower half, pushes the hydraulic fluid back to cylinders 15 through valve 28. The pistons 14 are pushed down and the levers 10 are returned to their original positions, this latter action being aided by the action of springs 16. In another embodiment Fig. 4, two retaining levers 10 are connected by rods 13, angular levers 30 and rods 34, 34a to armature 33 and permanent magnet 32 respectively. The magnet and armature are separated when the traction forces increase beyond a pre-set valve and after the obstruction has been passed springs 16' return the mechanism to its original position so that re-hitching can be effected. Figures 6 and 7 (not shown) illustrate a mechanical arrangement whereby an increase in traction force is transmitted to spring (35) which is compressed. This compression causes the forces on angular levers (30) to be reduced so that levers (10) give way to the traction forces and the pins of the implement are releasable.

II may be a phenol resol or an etherification product thereof with a C 1-4  alkanol or a condensate of HCHO with urea, ethylene urea, melamine, dicyandiamide, benzoguanamine, acetoguanamine or formoguanamine. The binder may be prepared by condensing a mixture comprising 99-50% by wt. of I with correspondingly 1-50% of II. The acid number of the product may be 60-100 and the viscosity of the product as a 50% solution in 2-butoxyethanol may range from B to Q (Gardner-Holdt). The binder may be prepared by first condensing I with a phenoplast followed by reaction with an aminoplast. For use as a coating composition the binder is neutralized with ammonia or a strong organic nitrogen base, e.g. diisopropanolamine. Conventional pigments and fillers may be present. In an example, a diglycidyl ether of bisphenol A is converted to a partial ester by reaction with a maleic acid/drying oil acid adduct. The partial ester is then condensed, in an inert gas with a butyl phenol resol.
